We gathered existing patches, fixed and improved what we could and
final result is an working charging driver with device-tree support
for Nexus 7.
At this moment charging works with:
- Nexus 7 2012 (grouper and tilapia)
- Nexus 7 2013 (flo and deb)
- ... and there are more devices equipped with these chargers.
Changelog:
v3: - The uint32 type now isn't specified for standard units in the SMB
DT binding because standard units already have a type.
Thanks to Rob Herring for the suggestion!
- The battery binding changes are rebased on top of the new battery.yaml
- The new battery temperature DT properties now have shorter names
and use <min max> format. Thanks to Rob Herring for the suggestion!
- Added new patch that adds SMB charger node to the new Nexus 7 2012
device-tree which has been merged into v5.9 kernel.
v2: - Addressed v1 review comments from Rob Herring and Sebastian Reichel
by moving out common battery properties from the charger node into the
battery-cell node.
- power_supply_register() of the SMB driver converted to resource-managed
API variant.
- Improved DT property names of the SMB binding by making them to follow
the generic power-supply naming scheme (-microvolts at the end, etc).
